By simply adjusting the electric field and surface charge density of each nanopore, rotational variables including speed, output power, and torque can be readily regulated in this work. The tangential force on the ssDNA is transmitted via electrostatic adsorption to the outer surface of the CNT, known as the rotor, resulting in the rotation of the nanomotor.
The selective ion transport through charged nanopores can generate a robust electroosmotic flow (EOF), which serves as the primary power for the movement of circular ssDNA. The central components of this nanomotor consist of a double-walled carbon nanotube (DWCNT) and a circular single-stranded DNA (ssDNA), which acts as the driving element for the nanomotor. Herein, we introduce a convenient manipulation method for controlling the rotation of a nanomotors assembled by CNT-DNA, which uses the electroosmosis effect within oppositely charged dual nanopores. Carbon nanotubes (CNT) are a crucial component of rotary nanomotors because of their excellent mechanical properties and adaptability to the human body. The rotary nanomotors is an important type of nanomotors, which is an essential step towards intelligent nanomachines and nanorobots. Inspired by nature, nanomotors have been developed, which have great potentials in microfluidics and biomedical applications.
